Description

Hydrophobierungsmittel Es wurde gefunden, daß sich die Einwirkungsprodukte von Formaldehyd auf die Additionsprodukte von Bisulfit an aliphatische Isocyanate mit io und mehr Kohlenstoffatomen sehr gut zum Hydrophobieren von Textilien eignen.Water repellants It was found that the action products from formaldehyde to the addition products of bisulfite with aliphatic isocyanates with 10 and more carbon atoms are very suitable for making textiles water repellent.

Solche Einwirkungsprodukte können z. B. in der Weise erhalten worden sein, daß man wäßrige Lösungen der Additionsprodukte von Alkalibisulfit an aliphatische Isocyanate mit io und mehr Kohlenstoffatomen, wie z. B. Oktadecyl-, Cetyl- oder Palmkernisocyanat, mit Formaldehyd, gegebenenfalls unter Zusatz von etwas Soda, behandelt. Ferner lassen sich entsprechende Einwirkungsprodukte verwenden, die auf der Grundlage von Isocyanaten aufgebaut sind, wie man sie aus Paraffinoxydationsfettsäuren mit io und mehr Kohlenstoffatomen oder durch Hydrieren von Rübölfettsäuren über die Amine herstellen kann, sowie solche Einwirkungsprodukte, in denen der io und mehr Kohlenstoffatome aufweisende Kohlenwasserstoffrest durch Heteroatome unterbrochen ist.Such exposure products can, for. B. been obtained in the manner be that one aqueous solutions of the addition products of alkali metal bisulfite with aliphatic Isocyanates with io and more carbon atoms, such as. B. octadecyl, cetyl or Palm kernel isocyanate, with formaldehyde, possibly with the addition of a little soda, treated. In addition, appropriate action products can be used that are based on are based on isocyanates, as they can be made from paraffin oxidation fatty acids with 10 and more carbon atoms or by hydrogenating rapeseed oil fatty acids can produce the amines, as well as those action products in which the io and hydrocarbon radical containing more carbon atoms interrupted by heteroatoms is.

Die gemäß der Erfindung in Betracht kommenden Einwirkungsprodukte von Formaldehyd auf Isocyanat-Bisulfitadditionsprodukte werden in der Weise für die Hydrophobierung von Textilien verwendet, daß man die Textilien mit alkalischen oder neutralen wäßrigen Lösungen oder Emulsionen der Produkte imprägniert, hierauf abquetscht oder abschleudert und abschließend, gegebenenfalls nach vorheriger Trocknung, einer Wärmebehandlung unterwirft, wobei Temperaturen von ioo bis iio° bei einer Einwirkungsdauer von einigen Minuten im allgemeinen genügen. Man kann die Einwirkungsprodukte auch in schwach saurem Medium, z. B. in essigsaurem Medium, verwenden. Weiterhin kann man sie zusammen mit Paraffin-Wachs-Emulsionen zur Anwendung bringen.The products of action that come into consideration according to the invention from formaldehyde to isocyanate bisulfite addition products are in the way for the hydrophobization of textiles used that one the textiles with alkaline or neutral aqueous solutions or emulsions of the products are impregnated thereon squeezed or spun off and finally, if necessary after previous drying, subjected to a heat treatment, with temperatures from ioo to iio ° at a An exposure time of a few minutes is generally sufficient. One can use the products of action even in weakly acidic Medium, e.g. B. in acetic acid medium, use. They can also be used together with paraffin wax emulsions.

Mit Hilfe der vorgeschlagenen Einwirkungsprodukte von Formaldehyd auf die Additionsprodukte von Bisulfit an Isocyanate mit io und mehr Kohlenstoffatomen ist es möglich, gegen Wäsche und gegen bei der chemischen Reinigung angewandte Lösungsmittel beständige Hydrophobiereffekte zu erzielen, und zwar in sehr einfacher Weise, bei verhältnismäßig niedrigen Temperaturen und in verhältnismäßig kurzer Zeit. Beispiel i Man imprägniert ein Baumwoll-Popeline-Gewebe foulardmäßig mit einer 6o° warmen Emulsion, die aus 3o kg Additionsprodukt von Natriumbisulfit an Octadecylisocyanat und 51 3oo/oigem Formaldehyd in iooo 1 Wasser von 8o° unter nachträglichem Zusatz von 51 ioo/oiger Sodalösung erhalten wurde, und trocknet anschließend in einem Rahmentrockner oder auf dem Filzkalander bei einer Temperatur von ioo bis iio°. Die Popeline ist dann fertig hydrophobiert.With the help of the proposed action products of formaldehyde on the addition products of bisulfite with isocyanates with 10 and more carbon atoms it is possible against laundry and against solvents used in dry cleaning to achieve stable water repellent effects, and in a very simple manner, at relatively low temperatures and in a relatively short time. example i A cotton poplin fabric is impregnated in the manner of a padding with a 60 ° warm Emulsion made from 30 kg of addition product of sodium bisulfite and octadecyl isocyanate and 51,300% formaldehyde in 100,000 water at 80 ° with subsequent addition of 51 ioo / o soda solution, and then dried in a frame dryer or on the felt calender at a temperature of 100 to 100 degrees. The poplin is then completely hydrophobicized.

Auch ohne Zusatz von Soda oder nach Ansäuern der Emulsion mit etwas Essigsäure erzielt man hervorragende Hydrophobiereffekte. Beispiel e Man imprägniert einen Baumwoll-Popeline-Mantel mit einer Emulsion, die man in der Weise bereitet hatte, daß man ein Gemisch von 40g des Additionsproduktes von Natriumbisulfit an Palmkernisocyanat und io g Paraformaldehyd in 2 1 Wasser von go° erhitzte und i g Soda hinzufügte. Der Mantel wird ausgewrungen, an der Luft getrocknet und hierauf heiß gebügelt; er ist dann waschbeständig hydrophobiert und behält diese Eigenschaft auch nach Reinigung mit hierfür in Betracht kommenden Lösungsmitteln, wie z. B. Benzin, Tetrachlorkohlenstoff, Trichloräthylen oder Benzol.Even without adding soda or after acidifying the emulsion with something Acetic acid produces excellent water repellent effects. Example e Impregnation a cotton poplin coat with an emulsion that is prepared in this way had that a mixture of 40g of the addition product of sodium bisulfite Palm kernel isocyanate and 10 g of paraformaldehyde in 2 l of water heated to go ° and i g of soda added. The coat is wrung out, air dried and then put on hot ironed; it is then wash-resistant and hydrophobized and retains this property even after cleaning with suitable solvents, such as. B. Gasoline, carbon tetrachloride, trichlorethylene or benzene.

Beispiel 3 30 g einer 4oo/oigen Paraffin-(Wachs-)Emulsion mit einem Gehalt von 7,5 % Natriumoleat füllt man mit Wasser von 6o° unter Umrühren auf 400 ccm auf. Hierzu gibt man eine Emulsion, die man aus 2o g des Additionsprodukts von Natriumbisulfit an Oktadecylisocyanat, gelöst in 6oo ccm Wasser bei go°, und 12 ccm 3oo/oigem Formaldehyd mit anschließendem Zusatz von 5 ccm ioo/oiger Sodalösung bereitet hatte.Example 3 30 g of a 400% paraffin (wax) emulsion with a content of 7.5% sodium oleate are made up to 400 cc with water at 60 ° while stirring. To this is added an emulsion which had been prepared from 20 g of the addition product of sodium bisulfite with octadecyl isocyanate, dissolved in 600 cc of water at 0 °, and 12 cc of 300 per cent formaldehyde with subsequent addition of 5 cc of 100 per cent sodium carbonate solution.

Mit der so erhaltenen Emulsion imprägniert man wann oder kalt Textilien beliebiger Art, trocknet beliebig, zuletzt jedoch bei Temperaturen von mindestens ioo°. Die Textilien sind nach dieser Behandlung waschecht und gegen Lösungsmittel beständig hydrophobiert. An- Stelle des in der Paraffin-(Wachs-)Emulsion verwendeten Natriumoleats kann man als Emulgatoren auch z. B. Additionsprodukte von Formaldehydbisulfit an Oktadecyldipropylentriarnin verwenden.The emulsion obtained in this way is used to impregnate textiles when or when cold of any kind, dries as desired, but ultimately at temperatures of at least ioo °. After this treatment, the textiles are washable and resistant to solvents permanently hydrophobic. Instead of the one used in the paraffin (wax) emulsion Sodium oleate can also be used as emulsifiers, for. B. addition products of formaldehyde bisulfite Use on octadecyldipropylenetriarnine.
